Unfortunately, I'm embarrassed to say, I can't seem to find any beehive-to-tub converters, which could turn this into heart on two tubs, the smallest heart variant, and the only known period 5 oscillator (that I am aware of) up to 26 bits without a synthesis, other than 17 versions of Elkies's P5, and several versions of Silver's P5.

I found two methods, both for eight gliders. This one proceeds via boat:

Did you find this from a soup? If so, could you please post a link to it? B heptominos are easy to synthesize, but they and their predecessors tend to move rapidly forward, so it's not easy to make one in a position where a beehive could be brought in behind it.

EDIT: Oops, never mind. While updating this in my archives, I noticed that I already had this synthesis - Extrementhusiast had created the same 9-glider synthesis on 2015-01-05, and I had made the same 1-glider reduction on 2015-08-24!

Half an hour after finding this, I found a way to make an converter (based on predecessors from many soups that use the same mechanism) that also makes this from 11 gliders, and gives the other unknown one from 14 gliders:

Heh. "Rich Holmes discovered"? I was asleep when apgsearch found this and woke up to find it'd been logged, tweeted, retweeted, reported here, used to make a smaller gun, deemed awesome, and written up on the wiki.
